Definitions

  • the improvement relates to a switching drive for the ink fountain roller of a printing machine according to the preamble of claim 1.
  • a switching drive of this type is described in DE-PS 1 000 400.
  • a solution to this problem is proposed according to the characterizing part of claim 1.
  • a spindle-nut connection with a very large pitch is used for this.
  • the spindle-nut connection is provided with an incline corresponding to the maximum travel of the switching drive. This enables the drive speed of the ink fountain roller to be adjusted from minimum to maximum step in just one revolution of the adjusting spindle.
  • the construction of the actuating gear is very simple in that only an actuating pin instead of a thread is necessary for the transmission of rotation.
  • the adjustment is further simplified in that a turning handle is provided on the adjusting spindle, which can be adjusted in small steps by means of a locking device.
  • the actuator 11 is shown in detail.
  • the adjusting spindle 13 is provided with a helical circumferential adjusting groove 17.
  • the adjusting groove 17 has a rectangular cross section and runs around the adjusting spindle 13 in only one turn. This means that the slope of the adjusting groove 17 corresponds at the same time to the maximum adjusting range of the adjusting spindle 13.
  • a drive nut 18 sits on the adjusting spindle 13. It is provided with a pin 19 which engages in the bearing lever 9 and in turn carries the pivot axis 8 of the link 7.
  • a screw 20 is inserted into the drive nut 18 and is provided with a guide pin 21 at its front end. The guide pin 21 engages in the adjusting groove 17 on the adjusting spindle 13.
  • the drive nut 18 When the adjusting spindle 13 is rotated, the drive nut 18 thus moves in the direction of the axis of the adjusting spindle 13 and thus moves the bearing lever 9.
  • either the connection between the drive nut 18 and the bearing lever 9 must be transverse to the axis of the Adjusting spindle 13 must be movable or the adjusting spindle 13 must be pivotally fastened to a small extent in the machine frame.
  • the locking device 16 ensures that the adjusting spindle 13 is secured against rotation.
  • the drive rod 14 is connected to the link 7 via the drive pin 15.
  • the connection to the ink fountain roller 1 is established via the sliding block 6, the drive pin 5 and the freewheel 3 connected to it, but only indicated here.
  • the drive movement is transmitted from the drive rod 14 provided with a double arrow to the link 7, which pivots about the pivot axis 8 and, depending on the relative position between the pivot axis 8 and the drive pin 5, takes the link block 6 more or less far.

Claims (4)

  1. Dispositif de commande du rouleau d'encrier d'une machine imprimante, comportant une roue libre agencée sur son axe, qui est reliée, sur un tourillon d'entraînement, à un entraînement oscillant par l'intermédiaire d'un coulisseau et d'une coulisse montée pivotante, l'axe de pivotement de la coulisse étant agencé de façon mobile par rapport au tourillon d'entraînement de la roue libre par l'intermédiaire d'un mécanisme de réglage,
    caractérisé en ce que le mécanisme de réglage (11) est une liaison broche-écrou de grand pas, et en ce que la partie déplacée axialement est reliée à un levier (9) monté pivotant dans le bâti de machine, portant l'axe de pivotement (8) de la coulisse (7).
  2. Dispositif de commande selon la revendication 1,
    caractérisé en ce que le mécanisme de réglage (11) comporte une broche de réglage (13) à gorge (17), dont le pas correspond à la zone de réglage maximale du mécanisme de réglage (11).
  3. Dispositif de commande selon les revendications 1 et 2,
    caractérisé en ce que le mécanisme de réglage (11) comporte un écrou de réglage (18), dans lequel, pour le couplage à la broche (13), est insérée une vis (20) portant une goupille de guidage (21).
  4. Dispositif de commande selon les revendications 1 à 3,
    caractérisé en ce que la broche de réglage (13) est reliée à une poignée tournante (12), grâce à laquelle, par interposition d'un dispositif à encliquetage (16), la broche (13) peut être réglée par petits pas angulaires.
